Configuring Ip Telephony; Selecting The Operating Mode - 3Com 3C10122 - NBX Business Telephone Installation Manual

Configuring IP
Telephony
Selecting the
Operating Mode
RFC 2132 (DHCP Options and BOOTP Vendor Extensions) defines vendor
specific options that allow you to configure the server to send locally
defined information to DHCP clients. NBX system devices support option
184. If you create and activate option 184 on your DHCP server, and use
it to specify the IP address of the NCP, you do not need to manually
configure the address on the NBX devices. For an example of how to
configure a DHCP server for option 184, see Appendix C, "Configuring
Option 184 on a Windows 2000 DHCP Server" in the NBX
Administrator's Guide.
Setting up IP telephony is the same whether you are installing the NBX
system for the first time or adding IP to an existing system. The steps for
setting up IP telephony are covered in these sections:

Selecting the Operating Mode

■
Configuring IP On-the-Fly
■
Configuring the DHCP Server
■
Manually Configuring Telephone IP Settings
■
To select the IP operating mode:
1 Log in to the NBX NetSet utility using the administrator username and
password.
2 Click the System-wide Settings > IP Settings.
3 Select the appropriate entry from the Network Protocol list. The choices:
Ethernet Only — Layer 2.
■
Standard IP — Every device requires an IP address. Either use DHCP
■
or manually assign the IP addresses.
IP On-the-Fly — The NCP provides IP addresses as needed to local
■
devices. Remote devices obtain IP addresses from the DHCP server, or
you can manually program their IP addresses.
4 Click Apply.
